Subject: Refactored/fixed race handling for bonuses that store it as a bitmask

- The following bonuses now work correctly with RC_DemiPlayer,
  RC_NonDemiPlayer, RC_NonDemiHuman, RC_Nonplayer:
  * bIgnoreDefRace
  * bIgnoreMdefRace
  * bDefRatioAtkRace
  * bAddMonsterDropChainItem (bonus3)
  * bAddMonsterDropItem (bonus3)
- A new function (map->race_id2mask) is provided, to easily and
  efficiently generate a bitmask from a race ID.
- The RC_ALL race ID is mapped to RC_BOSS and RC_NONBOSS, for backwards
  compatibility.
